Me personally, I liked Season 4 way more than Season 3. Both could of used improvements. Season 4a i thought was fine. Season 4b started off wack but picked up steam after 2nd episode.
season 1-2 were phenomenal television though.
i can live with the ending. I look at it more, that Jona is just over everything and it was close to being back to normal and he not gonna let anyone get in the way of that
only thing I dont get about the ending is:
if Ruth is majority owner of the casino, she got the fbi deal to launder the cartel money
but since narvarro sister killed her, what happens to that? No one can wash the cartel money now, and the fbi has no use for the cartel if they cant seize money that Ruth was supposed to update them about, and the whole point of the sister taking over the cartel was she wanted to be under the radar… but she effectively just killed the fbi deal
